MECHANISM OF ELECTRODE-REACTIONS OCCURRING IN THE PRESENCE OF FOREIGN NEUTRAL ADSORBABLE ORGANIC-COMPOUNDS

With the use of the thermodynamics of the surface phase the distinction between inhibitive properties of the equilibrium and non-equilibrium surfactant adsorption on energetically uniform and non-uniform surface is shown. It was pointed out that these properties additionally depend on the position of the reactant inside or outside the adsorbed layer. The respective equations are derived. On the basis of thermodynamic arguments the critical reassessment of the present understanding of the inhibition phenomena is performed. The possibility of the appearance of a limiting rate at higher coverages of the electrode by surfactant is discussed. © 1979 Elsevier Sequoia S.A.
